Problem with filen backend

What is the problem you are having with rclone?

Errors indicating something wrong is with dns:

It works unreliably, here is the problem with listing:

Looks like you have a DNS issue on your server as you can’t lookup the host. It should return:

nslookup gateway.filen-6.net
Server: 10.255.255.254
Address: 10.255.255.254#53

Non-authoritative answer:
Name: gateway.filen-6.net

Interesting. The problem is with quad9:

dig @9.9.9.9 gateway.filen-6.net

however other server returns correct values:

Yep, Quad9 is the only one failing that which is strange.
